Fig. 5. — Light regulation of genes of sulphate assimilation and GLS biosynthesis. Three-week-old Arabidopsis seedlings on MS-agarose plates were transferred to darkness for 44h. One part of these seedlings was re-illuminated by white light for 3h (dark/light), while the other part remained in darkness (dark). These plants were compared with plants continuing to grow in the normal day/night cycle (light). Transcript levels of genes involved in sulphur metabolism and GLS biosynthesis were determined by quantitative real-time PCR. The values for control plants (light) were set to 1. Data are presented as means ±SD from three pools of three seedlings. Asterisks mark significant differences between dark and light transcript levels, while the letter ‘a’ marks values significantly different between dark/light and dark samples (P < 0.05).
